Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine and namely to surgical gynecology. A laparoscopic access to the small pelvis is performed. A transverse skin incision is performed above the pubic symphysis along the midline, the aponeurosis and uterus are pierced with an awl needle to carry out two fixing non-absorbable ligatures and form sutures with the removal of the ligatures from the abdominal cavity through the uterus and aponeurosis. The body of the uterus is pierced closer to the right corner, 1 cm from the fundus of the uterus and from the right border of the uterus. After that the thread is removed from the needle with a clamp inserted into the trocar in the right iliac region and left in the abdominal cavity. The empty needle is removed from the abdominal cavity. The aponeurosis is re-pierced with the help of this needle in the incision on the anterior abdominal wall, 1 cm below the site of the previous injection. The body of the uterus is pierced with this needle without the thread closer to the isthmus on the right, 3-4 cm from the first puncture in the longitudinal direction. Then, after the first puncture, the left lavsan thread is pulled with a clamp and loaded into the hole of an empty needle passed through the body of the uterus closer to the isthmus. A needle with a thread is put into an incision on the anterior abdominal wall forming a longitudinal lavsan suture located closer to the right border of the uterus. In a similar way, a longitudinal lavsan suture is applied to the body of the uterus closer to the left border, while punctures with an awl needle through an incision on the anterior abdominal wall are performed with an offset to the left. A bipolar electrocoagulator is used to coagulate the peritoneum of the anterior wall of the uterine body between punctures and the peritoneum of the anterior abdominal wall between punctures, threads of longitudinally superimposed lavsan sutures introduced into the wound on the anterior abdominal wall are tied together. 
     EFFECT: method increases the strength of fixation of the uterus by increasing the number of points of its attachment to the anterior abdominal wall, the safety of the intervention by eliminating the possibility of the intestinal loop getting between the uterus and the anterior abdominal wall by obliteration of the vesicouterine space. Also, the method prevents the uterus from erupting with non-absorbable ligatures by imposing them in the longitudinal direction and at a sufficient distance from each other.

Abstract: FIELD: engineering. 
     SUBSTANCE: invention relates to the field of destruction of a material solid body (MSB) by at least two sources of local highly intensive heat impact (LHIHI), forming an impact area consisting of figures selected from a group: a rectangle, a triangle, a slot, assuming that the maximum concentration coefficient of thermoelastic stresses attributed to the interference of elastic waves in this area is achieved, and is aimed at providing effective modes of LHIHI sources on the surface of the MSB for destruction thereof, including technical apparatuses (TA), by reducing the ultimate tensile strength of the material of the solid body or reducing the load-bearing capacity of the structure of technical apparatuses made of metals, alloys, composite materials, as well as optical and optoelectronic apparatuses. Thermoelastic (thermal) stresses are a type of mechanical stress caused in the MSB by a change in the temperature or the unevenness of distribution thereof. Thermoelastic (thermal) stresses occur in the MSB due to the limited possibility of thermal expansion (compression) from the surrounding parts of the body or from other bodies surrounding the body. Thermoelastic (thermal) stresses can cause destruction of the MSB, parts and structural elements of the TA. LHIHI is understood as the impact of a heat flow source only on a certain (limited) part of the surface of the MSB in the form of a heat spot of various shapes, figures, and sizes. 
     EFFECT: provided effective modes of LHIHI sources on the surface of the MSB for destruction thereof.
